Re: st:how to transfer a value to another dataset

I am unclear what you mean by a "constant variable", nor is it clear
what -mppid- and -mcs- are in your data, but on one interpretation of
your problem you just type
gen double id = 4544 + _n
gen double cs = 10646 + _n
If the use of -double- here is mysterious, read
http://blog.stata.com/tag/format/
You can also do this
su ppid, meanonly
local mppid = r(max)
gen <whatever> = <something else> + `mppid'
and so on.
